Tricopter with Crius board finally flying but very unstable.

So I fixed the yaw problem by changing the thing to RC7_REV -1. IT is now flying.

I use the term flying loosely the thing is still an unstable mofo. It literally flies like crap. The allen screw on the left motor keeps backing out and I dont have a key small enough to tighten it all the way down. The right motor keeps having the prop locking screw back-out. The booms also have a habit of folding while in use too. I got it pretty stable at one point and it was still drifting a bit. So, I switched it into GPS position hold at about 25 foot altitude. This worked great for about 2 seconds and really stabilized everything. The thing then throttled down and dropped out of the sky.
